The use of dots and signs is again based on the SI. See for example section 6.1.6 in the 'Guide for the use of the International System of Units'. The +ve sign is redundant but I liked the symmetry and it felt better that leaving it out. and IMO underbars are overused in C++ already.
Here's an example of where a rigid specification (SI) is degrading the user experience. Picking an output format just because the SI says it is the one to use is a mistake. If the Boost community decides it's the right format, then it's the right format. But to preclude changes because it may contradict the formal SI standard seems shortsighted. I don't mind the dots. I could live with "*" as well. But I really don't like "+." I also tend to interpret it as signifying addition, not a sign value on an exponent. Using ^ or ** would help with that. -Dave
